Aircraft Information stored in what variable?

I have been using the DCS-ExportScripts mod to export aircraft information to my streamdeck.

So far so good using something like:

	local digAltitude = mainPanelDevice:get_argument_value(9) * 13000
ExportScript.Tools.SendData(2000, string.format("%d", digAltitude).." M") 

This works great for items available to mainPanelDevice.

Wondering if there is some type of global variable within the scope of exportscripts that I can find things like gun ammo still available, and how to call it within DCS-Exports

any info you may have may help poke me in the right direction and is appreciated.
